A new batch of cars will soon be built in Detroit, swelling the test fleet to 150, but then be shipped to California for actual testing. Clearly, the folks at Google are fair-weather motorists.

Apparently a "team in the hundreds" is now working on the project, split between California and Detroit. Apparently the Detroit workers are a mix of relocated Mountain View staff and locals—presumably hired for the automotive know-how.

There's little else new mentioned in the Detroit Free Press article. But honestly, the keeping of this project as all-American should be enough. [Detroit Free Press]
